[Kernel26-ck]Need some tips

Ypnose · 2011-06-10 21:48:51

Hey there,
Two days ago, I discovered this kernel. It sounds very good for my processor Phenom II. I really enjoy the work.
I read very often the wiki, it's so useful. I compiled it well but I just want to change some things as "Kernel Name" for example. Here my first question, can I change that name through nconfig?

Another thing, I tried to rename the .pkg. I edited PKGBUILD and I modified "pkgname=kernel26-ck" to "pkgname=kernel26-ck-Mad" but the name doesn't match.

My PKGBUILD:

## LOCALMODCONFIG OPTION
 # As of mainline 2.6.32, running with this option will only build the modules that you currently have
 # probed in your system VASTLY reducing the number of modules build.
 #
 # WARNING - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
 # Read, https://bbs.archlinux.org/viewtopic.php?pid=830221#p830221
 # To keep track of which modules are needed for your specific system/hardware, give my module_db script
 # a try: http://aur.archlinux.org/packages.php?ID=41689
 #
 # Note that if you use my script, this PKGBUILD will auto run the reload_data base for you to probe
 # all the modules you have logged!
 #
## USE CURRENT KERNEL'S .CONFIG
 # Enabling this option will use the .config of the RUNNING kernel rather than the ARCH defaults.
 # Useful when the package gets updated and you already went through the trouble of customizing your
 # config options.  NOT recommended when a new kernel is released, but again, convenient for package bumps.
## BFQ

I don't know what's wrong...

I know there is a repo with the packages but I want compile it myself. I tested packages from that repo, it rocks!

Thanks for the replies.
Best Regards

P.S. If you have a tutorial about all options to change via nconfig, give me it. There are so many things and it's a bit confusing.

There are several ways to do that, the easiest would be to adjust $_kernelname.
If you also want the package to be called kernel26-ck-mad you'll have to adjust the $pkgname array and the according funtions (package_kernel26-ck to package_kernel26-ck-mad. the same for the headers).

I suggest you use gconfig instead of nconfig. It will show info texts helping you understand the kernel options better. The rest is just practice.

This is what a customized PKGBUILD could look like: http://paste.pocoo.org/show/404305/
as patch: http://paste.pocoo.org/show/404304/

Have fun.

What demian posted should work just fine for you...

Ypnose · 2011-06-12 11:09:44

Thanks a lot, all of you!

Just wanted to say I found my "bible". It's called "Linux Kernel in a Nutshell" at http://www.kroah.com/lkn/
Cheers

graysky · 2011-06-12 14:06:12

Nice link, chapter 7 has a very nice little script for discovering which modules should be built into the kernel:

#/bin/bash
# http://www.kroah.com/lkn/ chapter 7
for i in `find /sys/ -name modalias -exec cat {} \;`; do
/sbin/modprobe --config /dev/null --show-depends $i ;
done | rev | cut -f 1 -d '/' | rev | sort -u

graysky · 2011-06-12 15:21:06

I modded it a bit to give nice output.
